APPARATUS FOR'MAKING FIREPROOF WALLS lN WOODEN BUILDINGS.

SPECIFICATION forming part Of Letters Patent No. 674,616, dated May 21, 1901.

A pli atio filed January 12,1901- Serial No. 43,035. (No model- To (0Z7, whom it may concern.-

Be it knownthat 1, JAMES A. MONAMEE, a citizen of the United States, residing. at Cambridge, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Apparatus for Making Fireproof. Walls in Wooden Buildings, of which the following is a specification.

This invention relates to an improved'apparatus for making concrete or plastic fireproof walls in wooden buildings; and it is particularly well adapted for making fireproof walls for elevator-wells, stairways, light and ventilator shafts, or making fireproof any room or portion thereof in a wooden building, as will hereinafter be more fully shown and described, reference being had to the accompanying drawings, wherein Figure 1 represents a side elevation of an elevator well or room, showing my method of making fireproof walls in wooden buildings. Fig. 2 represents a horizontal section of the finished wall previous to removing the moldboards. Fig. 3 represents a vertical section of the finished walls, showing moldboards removed. Fig. 4 represents a detail vertical section on the line 4 4 shown-in Fig. 2. Fig. 5 represents a vertical section on the line 5 5 shown in Fig. 2. Fig. 6 represents a detail perspective view of one of the removable clamping-hooks for holding the spacer or moldboards from spreading outward during the making of the plastic walls; and Fig. 7

. represents a detail perspective view of one of the T-headed nails for holding the inner spacer or moldboards at the proper distance inside of the wooden studs of the wall during the forming of the plastic wall.

Similar letters refer to similar parts wherever they occur on the diflerent parts of the drawings.

In the drawings, A A represent the floortimbers in the different stories in a building, and B B represent the floors supported on said timbers, as is usual in wooden buildings.

0 0 represent the Vertical wooden studs for the plastic walls, each such stud being provided on its interior portion with laterallyprojecting ribs 0 O, for a purpose as will hereinafter be described.

In making the concrete or plastic wall I proceed as follows: I place in contact with the exterior lower portion of the studs 0 O a moldboard D, and I secure to the interior of said studs the headed spacer or T-bolts E in such a manner as to cause their heads to extend a proper distance inside of the inner portion of said studs, as shown. I then place an inner moldboard F in such a position as to rest against the heads of the spacer-bolts E, thus causing the said inner moldboard F to be held at a proper distance away from the inside of the studs 0, as shown.

For the purpose of preventing the moldboards D F from spreading outward Iemploy a series of metal binders G, having at one end a T-head g and having a perforation in its other end adapted to receive a suitable locking-pin H, as shown in Fig. 6. After the spacer bolts or nails E have been driven the proper distance into the inside portion of the studs 0 O, I place the inner moldboard F in contact with the heads of the nails E, causing a space to be left between the inside of the said moldboard F and interior face of the studs 0 O, as shown. I then place the outside moldboard D against the outside of the said studs 0 O and lock said moldboards in position by means of the metal binder-hooks G, the head g of which is placed against the outside of one of the moldboards and the removable pin H against the outside of the other moldboard, as shown. I then proceed to add successive interior and exterior moldboards one above the other in the series to any height desired, and secure the same inposition by means of the headed spacer-nails E and binder-hooks Gr, after which I fill the space between said moldboards with concrete or suitable plastic material I, which is allowed to set and harden, after which I remove the moldboards, commencing from the top with the uppermost boards, and after withdrawing the pins H from the hooks G on the uppermost series of moldboards I draw out such hooks G and proceed downward in the same manner by removing successive moldboards and their hooks G until all the moldboards are removed, after which I pull out the spacer-nails E, which may be used over and over again in making other like walls.

By making the studs 0 with the laterallyextending ribs or side projections C O and by placing the inner moldboards Fat a proper I distance inside of said studs C, I cause the latter to be concealed on their interior poitions with the plastic material, so as to make the interior Wall portion of the well, room, or stairway perfectly fireproof. Said ribbed studs also serve to hold the plastic material thoroughly and firmly interlocked with the said studs. In this manner I am enabled to make durable fireproof Wallsin Wooden buildings at a very slight expense as compared with other devices for this purpose.

What I wish to secure by Letters Patent and claim is- 1. An apparatus for making plastic or concrete walls, consisting in combination with wooden vertical studs of two series of parallel superimposed boards, the outer series of such boards being arranged in contact with the outside of the studs and the interior series of said boards being arranged and held at a distance from the interior of said studs, a series of headed nails or projections for holding the interior boards at a suitable distance from the inner portions of the studs and a series of removable transverse clips arranged between the meeting edges of the boards for the purpose of securing the latter in position during the formation of the plastic or concrete walls, substantially as and for the purpose set forth.

2. In an apparatus of the character described, a series of vertical studs, a series of removable boards temporarily secured to and in contact with the exterior portion of said uprights, a series of removable boards arranged on the interior of the said uprights and held at a distance from the latter by means of headed nails or projections temporarily secured to said uprights, and a series of removable clips arranged between the meeting edges of the boards for the purpose of securing the latter in position during the formation of the plastic or concrete walls, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit-- HGSSGS.
